Is there any correlation between nail color and ones health?
Yes, nail color can indicate some health conditions, so, as a precaution, unexplained nail color should be discussed with a physician although there should be no need for panic. People suffering from circulation problems often will have nail beds of a blue or purple color. Keep in mind that regular use of nail polish can cause a harmless yellowing of the nails. Also, if your nails suddenly seem to be more brittle, it could be a hint that you are not taking care of your health.
